Fig. 39. Fossil invertebrates from a cold seep in the Pierre Shale, Didymoceras cheyennense Zone, AMNH loc. 3418, Custer County, South Dakota. A, B. Baculites corrugatus Elias, 1933, mature macroconch, AMNH 58552, uncoated. Note the series of small scalloped edges along the entire length of the body chamber on both sides (arrows), probably reflecting predation. A.

Text-fig. 3. CT slices on Block 3. Invertebrate moulds (a, c) and remains of their hard skeletons (a, b). Large areas of limestone matrix hold either only a few scattered invertebrates or no fossil at all (b, c). Ring artefacts seen close to the isocentre of the scan (b, c) are a well-known phenomenon caused by the X-ray beams traversing the block at an insufficient radiation dose (as expected in such a large block of dense material), and are not part of any physical structure present therein (Triche et al. 2019). in Hidden Treasures Uncovered: Successful Detection Of Fossils Below The Surface In Large Limestone Blocks Using A Standard Medical X-Ray Ct Scanner
